Answer:

22 degrees

Step-by-step explanation:

The total degree of a triangle is 180 degrees.

we are given two degrees already; 90 degrees (from the right angle sign) and 68 degrees from the problem. If we create an equation to reflect this we can find the missing angle:

180 = 90 + 68 + x

180 = 158 + x

x = 22

Step-by-step explanation:

<TSU=68

<STU=90

<SUT=

90+68=158

180-158=22

Answer:

Correct: Option a. negative reciprocals

Step-by-step explanation:

Perpendicular lines are defined as those who intersect at an angle of 90°.

There is an easy way to find out if two equations of lines correspond to perpendicular lines or not.

If line 1 is

y=m1x+b1

And line 2 is:

y=m2x+b2

The condition for the lines to be perpendicular is that:

m1*m2=-1

Solving for m2:

[tex]\displaystyle m2 = -\frac{1}{m1}[/tex]

As seen, both slopes are negative reciprocals.

Correct: Option a. negative reciprocals

Answer:

1: y=(3x/2)-4  2 :y=(-x/13)+(15/13) 3: y = 13x+55

Step-by-step explanation:

1:

Begin by finding slope

m = (y2-1)/(x2-1)

(-7-(-4)/(-2-0) = 3/2

next use point slope form

y-y1 = m(x-x1) (you can pick any point to use, I will use (0,-4)

y-(-4) = 3/2(x-0)

y+4 = 3x/2

y=(3x/2)-4

2:

The slope of the line y=13x+2 is 13

Take the opposite sign and reciprocal of 13 to get the slope of the line perpendicular; in this case it's -1/13

Next, just like in problem 1, use point slope form.

y-1 = (-1/13)(x-2)

y-1 = (-x/13)+(2/13)   (convert 1 to 13/13 for like terms and bring over to the left side)

y=(-x/13)+(15/13)

3:

the intercept will be $55 since it's the initial amount

you know that you deposit some amount every week so set this up as an equation

$133 = m(6)+$55     (the amount deposited every week times 6 +the initial $55 will equal $133)

solving for m gets you $13

so the equation is y = 13x+55

plug in 6 for x to check; 13x6 + 55 = 133

hope this helps

Answer:

B. y=1/3x+4

Step-by-step explanation:

The graph shows a line with a slope of -3. Perpendicular slopes is the reciprocal with a different sign (positive or negative). The perpendicular of -3 is 1/3, and B. is the only option with this slope.

Answer:

It’s c

Step-by-step explanation:

Answer:

Maximum of 50 persons

Step-by-step explanation:

Straight line equation

let the total prices be y

and the number of persons be x

1.  Brenda's Bridal Catering charges

the expression for the charges is

y=mx+c

y=18x+300---------------1

2.  Sarah's Complete Catering charges

the expression for the charges is

y=mx+c

y=15x+450---------------2

equating 1 and 2 we can then solve for the number of guest as

18x+300=15x+450

18x-15x=450-300

3x=150

divide both sides by 3

x=150/3

x=50

x<=50

Therefore she can invite a maximum of 50 persons

Answer:

Look at step-by-step explanation.

Step-by-step explanation:

First write everything in terms of sin and cos:

(sinx)(sinx/cosx) + (sinx)/(sinx/cosx) = (1/cosx)

Then simplify the expression where you can:

(sin^2)/(cosx) + (cosx) = (1/cosx)

Next find a common denominator and add the two numbers on the left side of the equation:

(sin^2)/(cosx) + (cos^2x)/(cos^2x) = (1/cosx)

((sin2^x)+(cos2^x)/(cosx)) = (1/cos)

Finally, use the identity, sin2^x + cos2^x = 1, to simply to numerator:

(1/cosx) = (1/cosx)

Answer:

Zoey cannot make enough 3/4-cup servings so that each person on the trip has one serving.

Step-by-step explanation:

Zoey made 9 1/2 cups of trail mix for a camping trip.

She wants to divide the trail mix into 3/4-cup servings.

Thirteen people are going on the camping trip.

This means :

1 person = 3/4 cup servings

13 people = x

Cross Multiply

13× 3/4

= 39/4

= 9 3/4 cup

So for Zoey to be able to serve 13 people the trail mix in 3/4 cup servings, she need 9 3/4 cups of the trail mix

From the she made 9 1/2 cups of the trail mix.

Hence, Zoey cannot make enough 3/4-cup servings so that each person on the trip has one serving.

Whenever the two numbers in a ratio are the same it means that they're equal. Hope this helps :)

Answer:

the y axis will be 1 and the x axis will be 8

I know that the y axis will be 1 because y=1  and I know that the x axis will be 8 because 2 to cubed will be 8 because when you multiply 2 by 2 you get 4 and when you multiply 4 by 2 the answer will be 8 so the axis will be (1,8)

Step-by-step explanation:

Answer:

62.5

Step-by-step explanation:

y∞x

y=kx( where k is the constant)

75=6k

75÷6 =k

12.5=k

therefore the relationship between k,x and y is y=12.5x

y=12.5×5

y=62.5

Answer:

It is C. I think

Step-by-step explanation:

A. will just make the investment smaller, not bigger, so not A. It is not B. because it does not give us the result we want. It's not D. because it is too high of an answer. I think it's C. I hope this helps, and I hope it's not wrong, but I do not think it is.
